While “Iron Man 2” filmed its main Huntington scene on the steps of the Munger Research Center, “Iron Man 3” broke new ground by becoming the first project to film INSIDE the Munger. The scenes are fairly subtle; in one, the Vice President (Miguel Ferrer) and his staff are in the White House Situation Room, watching the Mandarin’s actions with horror. For this scene, large green screens were installed along the walls of the Huntington’s President’s Conference Room. Some additional furniture was added by the production company, but the massive central conference table is always there. In the other scene, towards the very end of the movie, the VP is arrested and hustled away, as Rhodey (Don Cheadle) watches. The lobby and entrance area to the Huntington’s president’s office were lavishly decorated for Christmas, including an enormous two story tree. (A third shot was filmed outside on the lawn, where Rhodey, who is huddling near the wall of the Mandarin’s mansion, watches the suit fly overhead - but it doesn’t appear to be in the final film.)
